SAFETY DEVICE FOR PIPING.

To all whom it may concern:

Be it known that I, JOHANN KoENIo, a subject of the King of Bavaria, residing at 97 Alexanderstrasse, Riga, Russia, have invented new and useful Improvements in Safety Devices for Piping, of which the following is a specification.

The purpose of my invention is to provide means whereby the inconvenience attending the bursting of a water or other pipe can be readily remedied.

My invention is illustrated in the accompanying drawing, in which 7 Figure 1 shows piping fitted with one form of the new device, while Fig. 2 is a like view of piping fitted with a modified construction thereof.

In the piping a, pairs of T-connectingpieces 79 p, p p are inserted at certain distances apart, with intermediate valved devices 7" 1' The connecting pieces p, p are respectively furnished with casings t, 25 containing the respective valves 8, 8 In the event of the piping a bursting, for example, at w, the two valves 7', 1' located at the respective ends of the ruptured section, must be closed. The branch-pipe c has then to be connected, as shown, to two casings t t (normally kept closed by the valves .9, s whereupon the valves 8, s of these two casings t t can be opened, the branch 0 thus replacing the burst section of the piping a.

The arrangement illustrated in Fig. 2 differs from that just described only in as far that casings t t with valves 8 s are dispensed with, the flanged outlets of the connecting-pieces being closed by simple covers. On the piping a bursting, say at w, the two Specification of Letters Patent.

valves 1' 1' in advance of the burst section, and the two valves 7' r beyond it, must be closed. The-cover of the connecting-piece p which is located in advance of the valve 1, and the cover of the connecting-piece p which is located beyond the valve 9' have then to be removed and the ends of the branch-pipe 0 connected at these parts. It is then only necessary to open the valves 7' 0", the branch-pipe c establishing the continuity of the piping.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is 1. The combination with a pipe, of pairs of connecting pieces inserted at predetermined distances therein with a valve between the members of each pair, a. Valve for each connecting piece and a branch pipe connectible at its respective ends with the valves for the outer connecting pieces of any two consecutive pairs of connecting pieces, substantially as described.

2. In combination, a continuous pipe, pairs of T-shaped connecting pieces inserted at predetermined distances therein with a valve between the members'of each pair, a branch pipe connectible with the connecting pieces of any two pairs, said valves being adapted to close communication with a burst section.

In witness whereof I have hereunto signed my name this 13th day of May 1907, in the presence of two subscribing witnesses.
